Troubleshooting and error codes

Issues Solutions and Explanations
PC Connection A Mode Not Supported message appears: Set your PC's output resolution so it matches the resolutions supported by the TV (p. 18). If you are using an HDMI connection, check the audio output setting on your PC. The video is OK but there is no audio.
Poor picture First of all, please perform the Picture Test and confirm that your TV is properly displaying the test image. (go to MENU - Support - Self Diagnosis - Picture Test) (p. 30) If the test image is properly displayed, the poor picture may be caused by the source or signal.
The TV image does not look as good as it did in the store. If you have an analog cable/satellite box, upgrade to an HD digital set top box. Use HDMI or Component cables to deliver HD (high definition) picture quality. Cable/Satellite subscribers: Try HD stations from the channel line up. Antenna connection: Try HD stations after performing Auto program. Many HD channels are up scaled from SD(Standard Definition) contents. Adjust the Cable/Sat box video output resolution to 1080i or 720p. Make sure you are watching the TV at the minimum recommended distance based on the size and definition of the signal.
The picture is distorted: macro block error, small block, dots, pixelization. Compression of video contents may cause picture distortion, especially in fast moving pictures such as sports and action movies. Low signal level can cause picture distortion. This is not a TV problem. Mobile phones used close to the TV (within 3.3ft) may cause noise in picture on analog and digital channels.
Color is wrong or missing. If you're using Component connection, make sure the component cables are connected to the correct jacks. Incorrect or loose connections may cause color problems or a blank screen.
There is poor color or brightness. Adjust the Picture options in the TV menu. (go to Picture mode / Color / Brightness / Sharpness) (p. 22) Adjust Energy Saving option in the TV menu. (go to MENU - Setup) (p. 29) Try resetting the picture to view the default picture settings. (go to MENU - Picture - Picture Reset) (p. 24)
There is a dotted line on the edge of the screen. If the picture size is set to Screen Fit, change it to 16:9 (p. 23). Change cable/satellite box resolution.
The picture is black and white. If you are using an AV composite input, connect the video cable (yellow) to the Green jack of component input 1 on the TV.
When changing channels, the picture freezes or is distorted or delayed. If connected to a cable box, please try to reset it. (reconnect the AC cord and wait until the cable box reboots. It may take up to 20 minutes) Set the output resolution of the cable box to 1080i or 720p.
Sound Problem First of all, please perform the Sound Test to confirm that your TV audio is properly operating. (go to MENU - Support - Self Diagnosis - Sound Test) (p. 30) If the audio is OK, the sound problem may caused by the source or signal.
There is no sound or the sound is too low at maximum volume. Please check the volume of the device (Cable/Sat Box, DVD, Blu-ray etc) connected to your TV.
The speakers are making an inappropriate noise. Check cable connections. Make sure a video cable is not connected to an audio input. For antenna or Cable connections, check the signal strength. Low signal level may cause sound distortion. Perform the Sound Test as explained above.
No Picture, No Video The TV won't turn on.
The TV turns off automatically. Ensure the Sleep Timer is set to Off in the Setup menu (p. 26). If your PC is connected to the TV, check your PC power settings. Make sure the AC power cord is plugged in securely to the wall outlet and the TV. When watching TV from an antenna or cable connection, the TV will turn off after 10 - 15 minutes if there is no signal.
There is no picture/video. Check cable connections (remove and reconnect all cables connected to the TV and external devices). Set your external device's (Cable/Sat Box, DVD, Blu-ray etc) video outputs to match the connections to the TV input. For example, if an external device's output is HDMI, it should be connected to an HDMI input on the TV. Make sure your connected devices are powered on. Be sure to select the TV's correct source by pressing the SOURCE button on the remote control. Reboot the connected device by reconnecting the device's power cable.
RF(Cable/Antenna) Connection The TV is not receiving all channels.
The picture is distorted: macro block error, small block, dots, pixelization. Compression of video contents may cause picture distortion, especially with fast moving pictures such as sports and action movies. A low signal can cause picture distortion. This is not a TV problem.
Others Purple/green rolling horizontal bars and buzzing noise from the TV speakers with Component cable connection.
A "Mode Not Supported" message appears. Check the supported resolution of the TV, and adjust the external device's output resolution accordingly. Refer to the resolution settings on page 18 of this manual.
Caption on TV menu is greyed out. Caption can not be selected in the TV menu when connected via HDMI or Component or PC (p. 28). Caption must be activated on the external device (p. 28).
There is a plastic smell from the TV. This smell is normal and will dissipate over time.
The TV Signal Strength is unavailable in the Self Diagnostic Test menu. This function is only available with digital channels from an Antenna / RF/Coax connection (p. 30).
The TV is tilted to the side. Remove the base stand from the TV and reassemble it.
The channel menu is greyed out (unavailable). The Channel menu is only available when the TV source is selected.
Your settings are lost after 30 minutes or every time the TV is turned off. If the TV is in the Store Demo mode, it will reset audio and picture settings every 30 minutes. Change the settings from Store Demo mode to Home Use mode in the Plug & Play procedure. Press the SOURCE button to select TV mode, and go to MENU → Setup → Plug & Play → ENTER (p. 15).
You have intermittent loss of audio or video. Check the cable connections and reconnect them. Loss of audio or video can be caused by using overly rigid or thick cables. Make sure the cables are flexible enough for long term use. If mounting the TV to a wall, we recommend using cables with 90 degree connectors.
You see small particles when you look closely at the edge of the frame of the TV. This is part of the product's design and is not a defect.
POP (TV's internal banner ad) appears on the screen. Select Home Use under Plug & Play mode. For details, refer to Plug & Play Feature (p. 15).
The remote control does not work. Replace the remote control batteries with correct polarity (+/-). Clean the transmission window located on the top of the remote control. Try pointing the remote directly at the TV from 5~6 feet away.
